Automotive Lighting Q&A


How do LEDs Work?

Automotive LEDs are manufactured with two primary components: the LED chip which produces light and the heat sink which keeps the bulb cool. LEDs convert DC power and convert it to light. The heat sink captures the heat that dissipates from the light. While LEDs do produce significantly less heat than traditional incandescent bulbs, they do produce heat which must be managed.

LED’s produce electrical power which excites electrons. When an electron jumps from one state to another, it produces a small amount of light called a photo. LEDs essentially cause photons to be produced by continuously exciting electrons through electrical work. This process differs from a halogen or incandescent bulb which uses electrical current to heat a filament until it glows.

How do I find the brightest LED bulbs?

The brightness of an LED bulb is measured in lumens. A lumen is equal to the amount of light emitted by the bulb per second and is the universal measurement used to determine a lights brightness. In addition to lumens, another consideration is how many LED bulbs are used in your application. Generally speaking, the more LED bulbs, the brighter the light you will receive from the device.

What’s the difference between warm white and cool white?

White bulbs come in two temperatures. Cool white light generally has a temperature rating of 5000K and 8000k and produces a light similar to sunlight and fluorescent light. Warm white has a temperature in the 2500k to 4000k range and has a color more closely resembling incandescent lighting.

What is an LED panel?

An LED panel is a circuit board that includes multiple bulbs attached. A lighting panel replaces a single bulb to provide you with brighter lighting from multiple LEDs rather than just one.

My stock headlights are 55w, do I need 55w HIDs?

No. Becuase HIDs produce their light more efficiently than traditional halogen bulbs, they require less power to produce the same amount of light. 35w HIDs produce more than twice the amount of lumens than a 55w halogen bulb depending on the color temperature you choose. 55w HIDs produce about 40% more light than a 35w HIDs. A 35w HIDs create more than enough light for a low beam application which makes 55w low beams unnecessary. HIDs are not a good application for high beams because they take too long to fire up.

I’m looking for headlights with a slight tint of blue, what’s the best temperature color for me?

Any HID or LED headlight within a color range of 4300k to 12000k will produce a shade of blue. We recommend staying in the 5000K range or close to it to get your slight tint of blue while maintaining a white light and high level of visibility in the dark. Anything over 6000k will result in reduced visibility and light while driving in the dark.

Are HID/Xenon bulbs the same as HIDs?

No, Xenon bulbs are not true HIDs, they are merely halogen bulbs coated blue. HID bulbs require ballasts to regulate the level of electrical current used in the bulb to create the light. Coated blue halogen bulbs, especially the ones you find on eBay, typically do not perform very well and have a short lifespan. To get a true hyper white look for your lights and get the visibility you require out of your headlights; we highly recommend you stick to a HID or LED bulb for your headlights.

What is a HID relay harness?

Relay harnesses also referred to as dual in/dual out harnesses, are designed to pull the power for your headlights directly from the vehicles battery rather than the vehicle’s OEM wiring harness. These are a good option when upgrading your halogen bulb headlights from the manufacturer to HIDs because the factory harness may not be designed to handle the power requirements of a HID kit. HIDs require less operating power than halogens. However, they do require a considerable amount of power when they first ignite. If your wiring harness is designed for lower power halogen bulbs, you can experience misfires on your HID kit and risk electrical fires or damage by relying on the lower gauged wires of your factory harness.

A typical symptom of underpowered HIDs is that only one HID light will turn on. The factory harness has just enough power to handle the ignition of one light, but not both. You can typically get around this by turning your lights off and then back on again quickly, but this is not a good long term or safe option.

Another symptom you may experience with underpowered lights is your HIDs will flicker when they’re on as the electrical current in your factory harness is not constant enough to keep them on consistently.

Can I use HIDs for my high beams?

HIDs are typically not recommended for use on your vehicle’s high beam headlights. The reason for this is due to the delayed firing that HIDs experience when turning on. High beams are often used to flash on and off quickly, maybe to warn another driver or increase your visibility temporarily. The delay produced by HIDs will make this difficult or impossible. We recommend keeping your high beams as halogens or upgrading them to and LED bulb to match the color of your HIDs.

If you want to use HIDs for your high beams, you can accomplish that upgrade through the use of a HID relay harness. If you are already using or plan to use a relay harness for your low beam headlights, you’ll need a separate harness for your high beam HIDs.

What is an error code eliminator?

Modern vehicles have incorporated sophisticated monitoring systems in the vehicles computer system to warn the driver that your headlight is burned out. Typically when you upgrade or swap out your factory grade headlights for an upgraded system, your vehicle’s computer system will detect a different in voltage and turn on the headlight out warning light. An error code eliminator will tell your vehicles computer system that everything is fine and there is no need to turn on the warning light.
